+/**
+ * Preference storage class.
+ *
+ * This is a singleton that allows one to access the user preferences stored in
+ * the preferences.xml file. The preferences are stored in a file system-like
+ * hierarchy. They are generally typeless - it's up to the programmer to ensure
+ * that a given preference is always accessed as the correct type. The backend
+ * is not guaranteed to be tolerant to type mismatches.
+ *
+ * Preferences are identified by paths similar to file system paths. Components
+ * of the path are separated by a slash (/). As an additional requirement,
+ * the path must start with a slash, and not contain a trailing slash.
+ * An example of a correct path would be "/options/some_group/some_option".
+ *
+ * All preferences are loaded when the first singleton pointer is requested.
+ * To save the preferences, the method save() or the static function unload()
+ * can be used.
+ *
+ * In future, this will be a virtual base from which specific backends
+ * derive (e.g. GConf, flat XML file...)
